Changes to that this can build as of today on master

Remove the Thread Level Storage pieces (until TLS is in master)
update the hg tree so it builds the newest code
regenerate (automatically) the plist
Tell Chromium the correct path to our compilers.
Fix build issue.
pciutils needs to check for Bitrig.
The check looks if it finds cl in the compiler command, which is a Microsoft compiler and linker. Though, clang also starts with cl, which is then matched. This makes the check think, we're running some Microsoft compiler. Fixed.
NSS got a new Target OS. Add us after it.
Remove anachronisms in devel/cvs.

PERMIT_DISTFILES_CDROM ist kaput.
NO_REGRESS -> NO_TEST

distfiles still needs an update from openbsd for the getline() addition
to libc but ports no longer complains.
Fix previous gobject compile fix.
Chromium needs to know that Bitrig is also POSIX.
Chromium compile fix.
Allow binutils to use distributed libtool, not usr/bin/libtool

Fixes problem where it builds shared libbfd (that isn't shipped
or wanted)
